COMBINED WINDOW ORNAMENTAND VENTlLATOR.

SPECIFICATION forming part of Letters Patent No. 465,890, dated December 29, 1891.

Application filed May 26, 1891. Elerial No. 394,212. (No'mocleld To all whom it may concern.- Be it known that I, ABNER MULHOLLAND ROSEBRUGH, a subject of the Queen of Great I Britain,residing in the city of Toronto,in the county of York, Province of Ontario, Canada, have invented certain new and useful Improvements in a Combined WVindow Ornament and Ventilator, (Case 4,) of which the following is a specification.

This invention relates to an improvement in'windows.

The object of the invention is, first, to provide a window ornament or decoration, and, secondly, to construct and apply this windowornament so that it shall also constitute a simple and effective ventilating appliance. To accomplish this I place an ornamental guard at the upper part of the window and on the outside of the upper sash. This guard is made to represent or to imitate the appearance of a stained-glass window-sash, and it is so adjusted that there shall be no open space over the upper sash when the latter is lowered a few inches for the purpose of indirect ventilation.

Figure 1 is a diagrammatic front elevation 1) the upper sash, while 0 is a supplemental sash. d is the sill, while 6 is the head of the window-frame. lower rail, and g the meeting-rail, while p p are the vertical stiles. In the upper sash, 7b is the meeting -rail and p ,1) the vertical stiles. In the supplemental sash, j is the meet ing-rail, 7a the upper rail, and p p" the vertical stiles. p and p' are the pulley-stiles. cc 1) c are the panes of glass in sashes a, b, and 0, respectively.

Like letters indicate like parts throughout.

In Fig. 2, a is the lower sash, b the upper sash, and c the supplemental sash. r is the siphon-like Ventilating-space between sash a and sash b. The sash c prevents a direct draft through. the space 8 over the sash-rail o' In the lower sash,f is the of sash b. The meeting sash-rail j of sash c is extended inward at j, so as to more completely close the space between sash-rail i and saidsash-rail j.

Figs. 4 and 5 are vertical transverse sections of Fig. 1, taken through the sash-stile in the direction Y Y. 13 is the lower sash- -stile, p the upper sash-stile, and p the vertical stile of the extra sash c. d" is an extrahigh window-stool, which forms, also, the inside lower stop. 1; is a bolt for fastening the two sashes together. to is a slotted metal sheeting countersunk in stile p.

In Fig. 6, w u) w are slots or perforations in plate V for receiving bolt 1;. o is a tube passing through p for holding bolt In Fig. 7, c isthe supplemental sash secured to the outer side of the upper part of the window. The frame of the sash c is narrow and is secured to the outer stop of the window. The frame is preferably made a little narrower than the stop, so as not to interfere with closing of the outer shutters or with the fitting of the winter sash when either is used.

The operation of the first part of the invention is as follows: When the upper sash is lowered or the lower sash raised a few inches, they are locked or fastened together by passing bolt 12 into one'of the slots or perforations of plate 10. The sash opposite these slots or perforations is recessed so as to admit the bolt beyond the thickness of plate w. By means of bolt '0 and the recesses 10 w w' the overlapping sashes may be fastened so that the window cannot be opened from the outside.

The operation of the second part of the invention is as follows: Then the upper sash is lowered a few inches, the supplemental or extra sash c prevents a draft through the space between the upper sash-rail and the head of the window-frame. This device renders it possible to secure moderate ventilation by means of a gentle updraft through. the siphon-like space between the overlapping panes CL and b at r and asindicated by the arrow 15.

In the modification of the invention represented in Fig. 3 the lower sash is raisedyand a draft below the lower sash'rail is prevented by using the extra-high stool orinside stop (1.

The supplement-a1 or extra sash may be modified in many ways.- It is preferably made ornamental, and it preferably contains colored glass; but it may be made of opaque material. By making the extra sash c ornamental the sash will of course add to the appearance of the building when all the windows are equipped with said ornamental sash.

I purpose to equip several or all the windows of a dwelling or public hall with these ventilators, the object being to afford efficient ventilation without causing dangerous direct drafts.

I am aware that it is not new toplace a guard below or to the inner side of the lower sash-rail of the lower window-sash, so that said sash may be raised a fewinches without causing a draft below said window-sash. I am also aware that it is not new to place a perforated plate or wire-gauze at the outer side of the upper sash-rail of the upper sash for the admission of air when said upper sash is lowered. I do not claim either of these combinations.

I claim- 1. A window consisting of two sashes a and b and a guard c, said guard 0 being fitted to the upper part of the window-fran1e and on the outside of sash b, and said guard 0 being made ornamental and so as to imitate or repand also fitted to and between the two outside vertical window-stops, as and for the purpose set forth.

3. A window consisting of the inside and lower sash a, the outside and upper sash b, and the guard c, said guard 0 consisting of an outer sash-frame, and said frame inclosing colored or ornamental glass or its equivalent, whereby said guard 0 shall constitutea window ornament or decoration.

4:. A window consisting of the lower sash (1, upper sash b, and the outside supplemental sash or guard c, said sash I) being free to move in a vertical direction,and said sash or guard c forming a block to the free passage of air-currents over the top of sash b when said sash b is lowered a few inches for ventilatin'g purposes, substantially as described.

In testimony whereof I have signed my name to this specification in the presenceot two subscribing witnesses.
